Electro-sensitives are people who suffer from various physical and psychological ailments that they say are caused by electro-magnetic radiation (EMR) from ordinary household appliances, radios, televisions, cell phones, Wi-Fi, computer monitors, overhead power lines, and many other sources. The term is self-descriptive and not a medical term.
Double-blind, controlled studies have repeatedly shown that electro-sensitives can’t tell the difference between genuine and sham electro-magnetic fields (EMFs).1, 2 For example, a research team in Norway (2007) conducted tests using sixty-five pairs of sham and mobile phone radio frequency (RF) exposures. “The increase in pain or discomfort in RF sessions was 10.1 and in sham sessions 12.6 (P = 0.30). Changes in heart rate or blood pressure were not related to the type of exposure (P: 0.30–0.88). The study gave no evidence that RF fields from mobile phones cause head pain or discomfort or influence physiological variables. The most likely reason for the symptoms is a nocebo effect.”
A systematic review of 31 experiments testing 725 “electromagnetically hypersensitive” participants concluded:
The symptoms described by “electromagnetic hypersensitivity” sufferers can be severe and are sometimes disabling. However, it has proved difficult to show under blind conditions that exposure to EMF can trigger these symptoms. This suggests that “electromagnetic hypersensitivity” is unrelated to the presence of EMF, although more research into this phenomenon is required.
Twenty-four of these studies found no evidence supporting biophysical hypersensitivity. Seven reported some supporting evidence. “For 2 of these 7, the same research groups subsequently tried and failed to replicate their findings. In 3 more, the positive results appear to be statistical artefacts. The final 2 studies gave mutually incompatible results….metaanalyses found no evidence of an improved ability to detect EMF in ‘hypersensitive’ participants.1
Some electro-sensitives believe their cancer was caused by EMR. It is very unlikely that the kinds of things that electro-sensitives fear actually cause cancer. All electromagnetic radiation comes from photons. The energy of a photon depends on its frequency. “Roughly one million photons in a power line together have the same energy as a single photon in a microwave oven, and a thousand microwave photons have the energy equal to one photon of visible light” (Lakshmikumar 2009). Ionizing radiation is known to cause health effects; “it can break the electron bonds that hold molecules like DNA together” (Trottier 2009). “The photon energy of a cell phone EMF is more than 10 million times weaker than the lowest energy ionizing radiation” (Trottier 2009). Thus, the likelihood that our cell phones, microwave ovens, computers, and other electronic devices are carcinogenic is miniscule.
Despite the overwhelming scientific evidence against the view that our electronic gadgets are causing our headaches, nausea, Alzheimer’s, or stress, there are organized movements in several countries to enlighten the world about the dangers of EMR.
